Root-host validation for Tenant names is no longer needed here. The underlying issue (namespace.cozystack.io/host label exceeding 63-char limit) will be addressed in #2002 by moving the label to an annotation. Name length validation now only checks the Helm release name limit (53 - prefix length), which applies uniformly to all application types.
